Five female athletes from the UK travel across the globe, live with tribes and remote peoples, and take on local women in some extremely difficult and indigenous sports -- all wanting to be the Last Woman Standing -- in a series on BBC Three.

How will a group of very Western girls cope when they take on local women at sports they've been practising since they were children? How will they handle the rites of passage and the rituals, the harsh conditions and the reality of the ultimate life changing experience?

From Huka Huka Wrestling in Brazil to Bamboo Raft Racing in the Philippines and from Water Buffalo Racing in Indonesia to Tarahumara Mountain Endurance contests in Mexico, all five women are setting out with one aim -- to return with their pride and bodies in tact.

Over the course of their journey the athletes will be tested physically and emotionally... but by the end of the series only one Westerner will have the honour of being crowned the Last Woman Standing.

This episode: Kali -- Luzon, Philippines

Kali is a martial art with blades, sticks and hand-to-hand fighting which was traditionally performed by Filipino women as a form of defence whilst their men were away hunting. Kali is all about resilience and technique, and the athletes will face the harshest week of their lives learning the discipline of stick fighting in a remote martial arts training camp. According to kali tradition, in order to fight well, the athletes must be able to cope with pain and face their fears. Before training can begin the girls will have to prove themselves during a series of endurance trials, which will push them to their limits. They must demonstrate that they have the strength and will to fight, even after they are exhausted.
